174-acre lake near Québec. The lake tops out around 59 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
The drawn water covers 174 acres wrapped in 2.8 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. Roughly 13% of the water is 15 ft or less, the band where the food chain lives. Call it 1.2 mi long by 0.4 mi wide at the broadest reach. It sits in La Vallée-de-la-Gatineau MRC. Its nearest charted neighbour, Lac Bernard, is 9 mi to the south.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 18 to 59 ft, then a winter hold in 15 to 59 ft. Start at Deep basin. It's a deep basin holding about 59 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 18 to 59 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 15 to 59 ft | dawn | Deep basin (59 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 9 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

Spring puts brown trout in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 18 to 59 ft; cold water stacks them in 5 to 35 ft. Deep basin is the standout, a deep basin at roughly 59 ft, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
